No dome lights, radio, power windows or other electronics. Motor blower runs with no key! New battery, checked fuses, motor replaced less than 10,000 miles. have not found any rodent damage. Help!

 

You probably need to fix the ground located behind the passenger kick panel. It should look those this but it will likely be badly corroded or rusted out.

Here's the ground location in my truck.

Clean up a new spot higher up and reattach the wires and let us know if that helped

 

Thanks I'll try that as well all the grounds.
